HEATER.

SPECIFICATION forming part of LettersPatent No. 724,873, dated April 7,1903.

Application filed January 31, 1903. Serial No.- 141,278. 1 To model.)

To all whom it may concern:

Be it known that I, OTTO JAHELKA, a citizen of the United States, and aresident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Heater, of whichthe following is a full, clear, and exact description.

This invention relates to improvements in heaters or stoves,particularly heaters in which coal is used as fuel; and the object is toprovide a heater of simple construction and so arranged as to'give out ahigh and practically constant degree of heat with acomparativelysmall'am ount of fuel consumption, and, further, to providemeanswhereby the obnoxious gases generally rising from a fresh supply ofcoal are prevented from entering the-room in which the heater isplaced.'

I will describe a heater embodying my invention and then point out thenovel features.

in the appended claims.

Reference is to be had to the accompanying Referring to the drawings,l'designates the body of the stove, which may be of any desired shape,and, as here shown, it has doorclosed openings 2 3 at its oppositeside's, through which coal may be passed. The body 1 is supported on abase 4, which forms the ash-pit, and at one or more places in the wallof this ash-pit a door 5 is placed, the said door being provided withopenings designed to be regulated by a suitable damper.

Arranged between the body and the base isa grate 6, which is designed(in shaking down the coal) to be moved or rocked on a horizontal planeor around its axis. Upon removing the interior parts,.to be hereinafterdescribed, the grate may be tilted to dump the clinkers and othermaterial into the ash-pit. As here shown, at one side the grate has alug 7, which passes through a slot 8 in the. basering 9, and at theopposite side a rod 10 extends outward through a slot 11 in saidbasering, and this rod is provided with an angular end to be engaged bya suitable shaking or turning instrument. The body 113 provided with aremovable cover 12, having perforations 13 for the outlet of heated air,and these perforations 13 are regulated or closed by a perforateddamper-plate 14, mounted to rotate-on the upper side of the cover.

Arranged in the upper portion of the body is a cylinder 15. At its upperend this cylinder 15 has an outwardly-extended annular flange .16 forengaging with an annular. flange 17, formed in the upper portion of thebody. By this arrangementfthe cylinder 15 may be readily removed fromthe heater or placed therein. A grated cylinder 18 issupported from thecylinder 15 and is adapted to slide vertically with relation thereto. Ashere shown, the upper end of the grated cylinder 18 is provided with anannular flange 19 for engaging with an interior annular flange 20 at thelower end of the cylinder 15. Below the grated cylinder 18 is afunnel-shaped airreceiver 21. This air-receiver has a tubular extension22 at its lower end passing through a central opening in the grate 6 andcommunicating with the ash-chamber.

Mo vably arranged in the grated cylinder 18 is a regulating-cylinder 23,consisting of fire-clay or other suitable refractory material. At itsupper end this regulating-cylinder has an exterior annular flange 24 forengaging the flange 19 on the upper end of the cylinder 18, as clearlyshown in Fig. 1, and thus the said regulator-cylinder is suspended.

A lifting and regulating 'rod '25 passes through an opening in the cover12 of the heater and also through an opening in the damper 14. This rodextends loosely through an opening in a bar/26, connected to the upperend of the cylinder 23, and the lower part ofthis rod 25 is designed topass loosely through a notch 27, formed in a cross-bar28, connected tothe upper end of the air-receiver 21. This rod is provided below the bar26 with a transverse pin 29,designed to engage against the under side ofsaid bar 26, sothatthe regulating-cylinder 23 may be raised and held inthe position indicated'in Fig. 2 or may be wholly removed from theheater. When moving the said cylinder 23 alone, a pin on the lower endof the rod will be turned in such direction as to pass through the notch27. When it is desired to lift the air-receiver 21 with the cylinder 23for removing said parts from the heater, the said pin evidently must bemoved underneath said bar 28. The parts may beheld in elevated positionby engaging any one of a series of pins 31 on the rod 25 with the top ofthe damper 14, the said damper and stove top or cover being providedwith a slot through which the pins may pass.

In the operation when a fire is first started 'or fresh fuel is placedin the heater the regulating-cylinder 23 should be lowered to theposition indicated in Fig. 1, so that when in this position the gasesrising from the fuel will pass oif through the smoke-pipe 32, and atthis time air received through the opening or openings leading into theash-pit will pass up through the air-receiver 21, and thence into thecylinder, where it will become thoroughly heated and pass out throughthe openings 13 and 14 in a pure condition. After the obnoxious gasesshall have been burned away the regulating-cylinder 23 may be raised toany desired degree, permitting the hotair generated in the body of theheater to pass through the grated cylinder and mingle with the airreceived from the ash-pit. Obviously the air heated in the main body andthat heated in the cylinders will be of somewhat dilferent temperatures,but when mingled as above described a regular oreven temperature will bemaintained.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. A heater, comprising a body portion, a cylindersuspended from the upper portion of the body, a grated cylindersupported from the first-named cylinder, and an air-receivercommunicating with the cylinders and with the lower portion of theheater, substantially as specified.

2. A heater, comprising a body portion, a cylinder supported from theupper portion of the body, a grated cylinder supported from thefirst-named cylinder, a regulating-cylinderin said grated cylinder, andan air-receiver communicating with the cylinders and with the lowerportion of the heater, substantially as specified.

3. A heater, comprising a body portion, a cylinder suspended from theupper portion of the body, a grated cylinder supported from thefirst-named cylinder, a vertically-movable regulating-cylinder in thegrated cylinder, a grate in the heater, and an ash-receivercommunicating with the cylinders and having its open lower portionextended through said grate, substantially as specified.

4. A heater, comprising a body portion, a cover thereon having outletsfor air, means for regulating said outlets, a cylinder removablysuspended in the upper portion of the body, a grated cylinder removablysuspended from the first-named cylinder, a verticallymovableregulating-cylinder in the grated-cylinder, means for raising saidregulating-cylinder, and an air-receiver providing communication betweenthe cylinders and the ashpit of the heater, substantially as specified.

5. A heater, comprising a body portion, a cover therefor havingopenings, means for regulating said openings, a cylinder removablysuspended from the upper portion of said body, a grated cylinderremovably suspended from the first-named cylinder, 2. regulatingcylinder vertically movable in the grated cylinder, a funnel-shapedair-receiver communicating atits upper end with the cylinders andmovable vertically with relation thereto, a grate in the lower portionof the body, and a tubular projection from thelower end of saidair-receiver passing through said grate, substantially as specified.

6. A heater, comprising a body portion, a cover therefor havingopenings, means for regulating said openings, a cylinder removablysuspended from the upper portion of said body, a grated cylinderremovably suspended from the first-named cylinder, a regulatingcylindervertically movable in the grated cylinder, a funnel-shaped air-receivercommunieating at its upper end with the cylinders and movable verticallywith relation thereto, a grate in the lower portion of the body, atubular projection from the lower end of said air-receiver passingthrough said grate, and a rod for simultaneously lifting theregulating-cylinder and ash-receiver, substantially as specified.

7. In a heater, the combination with the body portion, of anair-receiving cylinder in the body and consisting of a plurality ofindependently-movable parts, one of said parts being grated, and meansfor regulating the grate-openings, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
